The Thermo Scientific Thermolyne Largest Tabletop Muffle Furnace provides triple the usable working area with two supplied accessory refractory shelves. Designed for safe operation, these furnaces are available in three temperature control models. They are ideal for annealing glass, determinations of volatiles, catalyst research and ashing organic and inorganic samples.

Features of the F30438CM Furnace

Includes the D1 Digital Controller (see below for alternate controllers). Programmable with four (4) stored program of sixteen (16) segments. Each segment includes one ramp and one dwell, so you can create four programs with 16 ramp/dwell cycles. The ramp is used to vary the heat-up rate to your specified setpoint. The furnace will then dwell (hold the temperature) at a set level for a specified time. An LED display simultaneously shows both setpoint and actual furnace temperatures. A mechanical overtemperature protection relay and RS-232 communications interface are also included. You are viewing the D1 version.

User-selectable overtemperature protection

Open thermocouple protection

Adjustable power output from 1 to 100%

Heating elements are on chamber top, bottom and sides for enhanced temperature uniformity

Built-in vent port removes undesirable contaminants and moisture to extend the life of the element and unit

The F30438CM furnace includes the D1 digital controller and is also available with alternate digital controllers allowing for various levels of control and programs.

B1 - Single setpoint with one ramp and one dwell. The ramp is used to vary the heat-up rate to your specified setpoint. The furnace will then dwell (hold the temperature) at a set level for a specified time. Single display shows actual temperature or setpoint. A mechanical overtemperature protection relay is also included.

C1 - Programmable with one (1) stored program of eight (8) segments. Each segment includes one ramp and one dwell, so you can program 8 ramp/dwell cycles. The ramp is used to vary the heat-up rate to your specified setpoint. The furnace will then dwell (hold the temperature) at a set level for a specified time. An LED display simultaneously shows both setpoint and actual furnace temperatures. A mechanical overtemperature protection relay is also included.
